Wattgamma-,1 Be it known that Ij',i J3.REnniKBosrno IBtrnL, a subject ofthe Kiiig. of Norway," residing at Similar Purposes,

- Ghristiania, Norway,

have invented certain new and useful Improvements in AutomaticRegistering Machines for Statistical and of which the following is aspecification.

' This vinvention relates to machines for registering statisticalpandlike particulars of the type in which cards provided with erforationscorresponding to various numrs are usedtoclose electrical circuits bymeans of brushes making contact through the said perforations, theclosing of .said electrical circuits actuating the registeringmechanism. I

This invention also relates to selecting apparatus for use inregistering machines of the type in which insulated contact platesarranged inone or, more arcs are provided and one or more selector-armsare adapted to rotate synchronously with the card feed ing mechanism soas, to make rubbing contact withfthe said contact plates.

'Acc'ordin to thefi present {invention the adding mec anism in a machineof the above and a plurality of toothed addin type consists of amutilated {toothed wheel hav ng nine teeth only,- rotatingsynchronously'with the card feeding mechanism, wheels each of whichadding wheels is a apted to be re1eased by an electromagnet'so as to engage with atoothflonthe mutilated wheel corresponding to thenumbenindicated by the erforation on the card and-to be rotate acorresponding number of teeth.

The invention also consists in a selecting chine of the ty e referredtozabove'charac terized by the eature'that'forl each arc of contactplates there is provided "a single electro-magnet which can be,connectedto one or more of thfiontaetsfin the said arc; the saidelectro-mag'nets{actuating a switch to close a circuit'ready for;operating either the adding mechanism or a special flap for separatingout the 'cardsor. for both, said" switch closing the circuit. nly on allthe electro-magnets being actuated Referring now to the accompanyingdraw- 111 ig. 1 is a diagrammaticview showing the operation of theregistering and selector mechanisms and 'Wheels. w

ri 2 is a detailed view of the adding In Fig. 1 of the drawings the.cards are moved by means of a feed device H one by one passed theselector contacts V V and registering contacts T T T,. On the same axisas the feed device there are provided rubbing contacts a, and 0 which,during the rotational motion, rub over arc-shaped contacts O 0,. Thesearc. contacts consist of plates insulated from one another andcorrespond in number with the number of numerals in the vertical columnsof the cards. One or more of the plates in the are contacts O C areconnected by means of a contact board wit-h the locking magnets R Rrespectively. The whole arrangement is such and the parts are relativeto one another in such a manner that the rubbing contacts 0,, 0 -con1einto contact with the plate which bears the same number as theperforation through which the brushes V or V is in meshing contact. feeddevice there is arranged further, .a broad toothed wheel D which servesto rotate the counting pinions E E E in the adding operation. Thistoothed wheel I) has nine teeth which are so arranged in're'- lation tothe counting wheels that immediately one of the contact brushes T T and:T comes exactl bers on the car the correspondingly numbered tooth of thewheel D will be situated exactly in front of the point of its engagementwith the adding pinions. t

The improved machine comprises further an' electric battery K, lockingmagnets. and; clutches hereinafter describe If, for instance, it isdesired to select all the engineers in a certain town and at the sametime add their respective incomes to-' ether and it is assumed thatengineers in this town are represented by the numbers 7 and 3 in thefirst and second columns all the cards are perforated in the first twoparticulars as shown. The three columns on the right of the card maycontain, for'instance,

On the same axis .as the opposite one of the numthe incomes stated inthousands," hundreds and tens of dollars. stance, $6,470.

As the card is being .fed in the direction of the arrow the contactbrush V will come through the hole 7 into contact with the In this case,for indrum and thus close a circuit extending from the battery K throughthe axle, the contact this sheet plateof theigroup 01 which is Idesignated 7 the locking magnet R brush V,, the; drum, and thus backhasbeen released.

. this means contact to the battery. By this means the locking magnet Rreleases partly the contact R n the electric circuit for the counter,but in such manner that the contacts R and G can be closed only afterthe locking magnet B, 'By a further feed of the card' he brush V inpassing over the hole 3 in the'card closes the circuit extending fromthe battery through the axle, the contact 0 the contact plate of thegroup G which is designated 3, the locking magnet R and again throughthe brush V the drum, and thus back to the battery.

the adding wheel E which is rotatably mounted on the end of a spring--actuated lever, -No. 7 of the mutilated toothed Wheel D comes into meshwith tooth which consequently rotates the adding wheel E in the forwarddirection to the extent of 7 teeth.

The lever is pivoted'about a shaft P.

- On this shaft is also rotatably mounted an other adding wheel 0similar to E to which the number ring S is attached.

The toothed wheel Dis provided with a cam L which resets the lever Nbehind the i 'stop Q on the armature M since this is held against thelever N by means of a spring and thus takes the wheel E out of mesh withthe mutilated-wheel D. The wheel .E is now ready to be engaged againwith the teeth on D.

'The wheels E, and E, are mounted and operated in the same manner .asE

Similarly the addingpinions E will be rotated forwards to the extent o'fl and 6 teeth respectively. At each revolution of the drum the addingwheels. are

. brought out of mesh, whereupon the. number beingcarried forward isadded in the same way as in ordinary adding machines.

Below the feed drum there is provided a flap (not shown) which opens atthe same time as thecontact arm R. which turns'down to the screwterminal G.- By the opening of this flap all the cards that. haveeffected a release of the magnets R and R are separated out.

readily understood that all those cards that have their perforatedselected ing more than two figures by simply providing a correspondingnumber of locking magnets and selecting arcs. The locking magnets mustbe so constructed that immediately all the magnets have been released,the machine will then only be able to register one or more statisticaldata for the card groups which have produced the release of the magnets.In' the same manner a plurality of rows of counters may be provided foreffecting the simultaneous addition of a plurality .of particulars onthe cards.

By connecting the locking magnets with a plurality ofcontact plates onthe selector arcs O 0,, it is possible by'means of a series of selectorbrushes to separate out and register a plurality of groups of cards. Forinstance, if it is desired in addition to group '73 to separate out andregister also groups 74, 75, and 76 the operator has merel toconnectthecontact plates 4:, 5 and 6 o the are C with the magnet R so thatthe'locking.

pawls of this magnet will be released, also all cards whose numbers 4, 5and 6 are per-- forated in the same column in addition to being releasedby the cards that are perforated at No. 3.

In the example here given the counter is employed in combination withthe selector mechanism. It is however obvious that the counter can beused by itself.

A machine for registering statistical and likeparticulars-comprlsing a movable carrier'for cards perforated accordingto the particulars to b'e registered, aplurality of brushes resting onsald carrier, electrical (Trcuits including saidcarrier and brushes, anadding mechanism comprising a mutilated toothed wheel having nine teethmoving synchronously with the carrier, a plurality of' toothed addingwheels, and an elec- L tr o-magnet associated with each of said add .ingwheels and included 1n said circuits,
